304 stainless steel pipe is usually sold as stainless steel pipe with a length of 6M. After processing is made into a variety of stainless steel tube products widely used in daily life.

But in fact, 304 stainless steel pipe in the processing of various problems often occur. Simply give you a summary of the problems that are likely to occur in the processing of 304 stainless steel pipe and the solution.

1,304 stainless steel pipe after low temperature and high temperature finishing, welded stainless steel pipe may appear welding defects, mechanical damage, for specific cases, when necessary, the need for mechanical repair, but also according to the stainless steel pipe rust or spots for certain pickling, passivation steps. But if only the weld is pickled and passivated, it also causes the surface to be uneven and affects the aesthetics.

2, manual grinding and polishing after pickling passivation treatment, for a larger area of the workpiece, it is difficult to achieve uniformity and consistency of the treatment effect, can not get the ideal uniform surface. And the cost of labor time and auxiliary materials is also higher. So after the completion of those surface treatment, in order to brighten the overall brightness of the stainless steel tube, so that it is more able to meet the general needs of normal use and decoration, you can choose to use polishing technology.

3, followed by the elimination of rust on the surface of stainless steel tube, the potential for corrosion. Stainless steel tube hot and cold alternating processing can promote the stainless steel material to obtain better strength and corrosion resistance. However, this kind of processed stainless steel pipe material is prone to porosity, cracks, slag and so on when welding. Some corrosive environments are prone to corrosion of stainless steel pipe. This situation requires the use of appropriate mechanical treatment and chemical action to enhance the corrosion of stainless steel pipe, in order to extend the use of stainless steel pipe.

4, in 304 stainless steel tube processing, due to its unique hardness, making the tool wear faster, and more difficult to chip; stainless steel tube processing, the use of high thermal conductivity tool; and stainless steel tool needs to be equipped with good toughness, as well as high strength of the cutting edge and the combination of the coating film. The use of sharp cutting edge edge line and wider chipbreaker groove edge band, which can reduce the cutting pressure, but also a good control of the processing of the chip removal;.

5. Due to the low thermal conductivity of stainless steel tube processing easily caused by the plasticity of the cutting edge to produce deformation and accelerate the degree of tool wear;. To choose the appropriate processing conditions in order to maintain the service life of the tool.
